A window into the invisible wound of war: Functional neuroimaging of REM sleep in returning combat veterans with PTSD

Relative regional cerebral metabolic rate of glucose in rapid eye movement (REM) sleep and wakefulness was explored in combat veterans with and without posttraumatic stress disorder PTSD, using positron emission tomography. Hypermetabolism in brain regions involved in arousal regulation, fear responses, and reward processing persist during REM sleep in combat veterans with PTSD. ? 2012 Elsevier Ireland Ltd.
